Is it best practice to have a canonical tags on all pages
-
The website I'm working on has no canonical tags. There is duplicate content so rel=canonicals need adding to certain pages but is it best practice to have a tag on every page ?
-
ColesNathan,
Have you seen what Google has to say about canonicals? https://support.google.com/webmasters/answer/139066?hl=en
You might find it helpful. They list reasons why you might want to use a canonical tag including those identified above and a few others, for example, for letting Google know your priorities when it comes to crawl budget and SERP display.
Canonicals can also help undermine plagiarism. If scrapers leave your self-referencing canonical intact, it will tell Google you are the originator of that content and consolidate link signals into your URL.
-
Correct, I would usually advise adding in a self-referencing canonical tag to make it easier for audits and search engines to understand what the actual content is on the page.
-
Hi, thanks for getting back to me. Ok so you don't need a canonical on every page unless its required.
However, for tracking purposes it is good practice to have one set up on all pages?
Have I got that right ?

Hi there!
It is a best practice as long as you have a CMS or any system that allows you to control them. In the case of Wordpress with YOAST it is pretty easy to set up.
Why would you want a canonical on every page? This is useful when you have different campaigns and you use url parameters for tracking (the common _utm from Google analytics), and that is correctly taken care of with wordpress+YOAST.If you see that you dont need canonicals on any page, then dont use it. Just be sure that when generating parameters o duplicate content, there is a canonical.
Hope i´ve helped.
Best luck.

Spammy page with canonical reference to my website
A potentially spammy website http://www.rofof.com/ has included a rel canonical tag pointing to my website. They've included the tag on thousands of pages on their website. Furthermore http://www.rofof.com/ appears to have backlinks from thousands of other low-value domains For example www.kazamiza.com/vb/kazamiza242122/, along with thousands of other pages on thousands of other domains all link to pages on rofof.com, and the pages they link to on rofof.com are all canonicalized to a page on my site. If Google does respect the canonical tag on rofof.com and treats it as part of my website then the thousands of spammy links that point to rofof.com could be considered as pointing to my website. I'm trying to contact the owner of www.rofof.com hoping to have the canonical tag removed from their website. In the meantime, I've disavowed the www.rofof.com, the site that has canonical tag. Will that have any effect though? Will disavow eliminate the effect of a rel canonical tag on the disavowed domain or does it only affect links on the disavowed website? If it only affects links then should I attempt to disavow all the pages that link to rofof.com? Thanks for reading. I really appreciate any insight you folks can offer.

Htaccess - Redirecting TAG or Category pages
Hello Fellow Moz's, We have an issue redirecting some /TAG and /Category pages to inner pages. As an example we use: RedirectMatch 301 /category/Sample-Category(.*) https://OurDomain.com.au/New-Page//$1 That works well. The issue is we have other categories and tags that are named similar to /Sample-Category As an example, if we try to redirect /Sample-Category-1 to /New-Page-1 - it will not work, and redirects to /New-Page I assume this is because /Sample-Category is already being redirected, so anything after /Sample-Category like -1 or -2 or -3 etc, will not be recognized. Anyone know of a workaround?

Duplicate Content www vs. non-www and best practices
I have a customer who had prior help on his website and I noticed a 301 redirect in his .htaccess Rule for duplicate content removal : www.domain.com vs domain.com RewriteCond %{HTTP_HOST} ^MY-CUSTOMER-SITE.com [NC]
Intermediate & Advanced SEO | | EnvoyWeb
RewriteRule (.*) http://www.MY-CUSTOMER-SITE.com/$1 [R=301,L,NC] The result of this rule is that i type MY-CUSTOMER-SITE.com in the browser and it redirects to www.MY-CUSTOMER-SITE.com I wonder if this is causing issues in SERPS. If I have some inbound links pointing to www.MY-CUSTOMER-SITE.com and some pointing to MY-CUSTOMER-SITE.com, I would think that this rewrite isn't necessary as it would seem that Googlebot is smart enough to know that these aren't two sites. -----Can you comment on whether this is a best practice for all domains?
-----I've run a report for backlinks. If my thought is true that there are some pointing to www.www.MY-CUSTOMER-SITE.com and some to the www.MY-CUSTOMER-SITE.com, is there any value in addressing this?0 -
What's the best way to redirect categories & paginated pages on a blog?
I'm currently re-doing my blog and have a few categories that I'm getting rid of for housecleaning purposes and crawl efficiency. Each of these categories has many pages (some have hundreds). The new blog will also not have new relevant categories to redirect them to (1 or 2 may work). So what is the best place to properly redirect these pages to? And how do I handle the paginated URLs? The only logical place I can think of would be to redirect them to the homepage of the blog, but since there are so many pages, I don't know if that's the best idea. Does anybody have any thoughts?

Dynamic pages - ecommerce product pages
Hi guys, Before I dive into my question, let me give you some background.. I manage an ecommerce site and we're got thousands of product pages. The pages contain dynamic blocks and information in these blocks are fed by another system. So in a nutshell, our product team enters the data in a software and boom, the information is generated in these page blocks. But that's not all, these pages then redirect to a duplicate version with a custom URL. This is cached and this is what the end user sees. This was done to speed up load, rather than the system generate a dynamic page on the fly, the cache page is loaded and the user sees it super fast. Another benefit happened as well, after going live with the cached pages, they started getting indexed and ranking in Google. The problem is that, the redirect to the duplicate cached page isn't a permanent one, it's a meta refresh, a 302 that happens in a second. So yeah, I've got 302s kicking about. The development team can set up 301 but then there won't be any caching, pages will just load dynamically. Google records pages that are cached but does it cache a dynamic page though? Without a cached page, I'm wondering if I would drop in traffic. The view source might just show a list of dynamic blocks, no content! How would you tackle this? I've already setup canonical tags on the cached pages but removing cache.. Thanks

Best practice for removing indexed internal search pages from Google?
Hi Mozzers I know that it’s best practice to block Google from indexing internal search pages, but what’s best practice when “the damage is done”? I have a project where a substantial part of our visitors and income lands on an internal search page, because Google has indexed them (about 3 %). I would like to block Google from indexing the search pages via the meta noindex,follow tag because: Google Guidelines: “Use robots.txt to prevent crawling of search results pages or other auto-generated pages that don't add much value for users coming from search engines.” http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35769 Bad user experience The search pages are (probably) stealing rankings from our real landing pages Webmaster Notification: “Googlebot found an extremely high number of URLs on your site” with links to our internal search results I want to use the meta tag to keep the link juice flowing. Do you recommend using the robots.txt instead? If yes, why? Should we just go dark on the internal search pages, or how shall we proceed with blocking them? I’m looking forward to your answer! Edit: Google have currently indexed several million of our internal search pages.

Best Practice for Inter-Linking to CCTLD brand domains
Team, I am wondering what people recommend as best SEO practice to inter-link to language specific brand domains e.g. : amazon.com
Intermediate & Advanced SEO | | tomypro
amazon.de
amazon.fr
amazon.it Currently I have 18 CCTLDs for one brand in different languages (no DC). I am linking from each content page to each other language domain, providing a link to the equivalent content in a separate language on a different CCTLD doamin. However, with Google's discouragement of site-wide links I am reviewing this practice. I am tending towards making the language redirects on each page javascript driven and to start linking only from my home page to the other pages with optimized link titles. Anyone having any thoughts/opinions on this topic they are open to sharing? /Thomas0
